A trampoline safety net enclosure is a trampoline accessory that significantly reduces the chance of fall off and frame impact injuries. ==History== The first commercially successful trampoline safety net enclosures were invented and patented by Mark Publicover in the United States and first sold there in 1997 by JumpSport Trampolines. By 2006 80% of all new trampoline sales included safety net enclosures.〔(【引用サイトリンク】 Trampoline–Safety–Facts )〕
